The Peoria County Sheriff's Department said in a news conference that a family member called deputies to the Princeville home Sunday around 10 p.m. CT (11 p.m. ET) for a suspected burglary. When deputies arrived, they found blood in the home, sheriff Brian Asbell said.

Brill De Ramirez and Barron were not at the house sparking a search for the couple. The sheriff's department released a statement on Facebook Monday night announcing that an arrest was made and Brill De Ramirez and Barron are deceased.

Authorities have not released details on what led to the arrests, but Asbell said they were based on a confession, NBC-affiliate KXAS-TV reports.

Deputies believe the bodies are somewhere in Henry County but have not yet located them. Asbell said he believes Brill De Ramirez and Barron were killed Friday morning.
